Load Intrinsics

Intel® Streaming SIMD Extensions 2 (Intel® SSE2) intrinsics for integer load operations are listed in this topic. The prototypes for Intel® SSE2 intrinsics are in the
emmintrin.h
header file.
To use these intrinsics, include the
immintrin.h
file as follows:
#include <immintrin.h>
The results of each intrinsic operation are placed in registers. The information about what is placed in each register appears in the tables below, in the detailed explanation of each intrinsic.
R
,
R0
, and
R1
represent the registers in which results are placed.
